Large Area Smart Piezoelectric and Pyroelectric Sensors.

Abstract

In the seventh interim report an account was provided of the embedment of a composite transducer within a reinforced epoxy laminate structure for use as an in-situ acoustic emission (AE) sensor, strain gauge or ultrasonic detector/transmitter for NDT techniques. The present report is concerned with the further investigation of the suitability of these composite materials as both surface mounted and embedded AE sensors. Particular attention has been focused on the detection on acoustic waves in structures which possess plate-like geometry where the propagation of acoustic waves are constrained to definite modes.
